Has A Vital Deep Ocean Current Weakened by 26% Since 2014? — Yes and No

This blog post and the “Deep Dive” podcast, created by NotebookLM, are based on “Observed decrease in Deep Western Boundary Current transport in subpolar North Atlantic” by Koman et al. (2024). Scientific analysis of the Deep Western Boundary Current (DWBC) off the southern tip of Greenland reveals a 26% decline in transport between 2014 and... Continue Reading →

The North Atlantic ‘Cold Blob’ of 2015: It Wasn’t Caused by a Collapsing Ocean Current

This blog post and the “Deep Dive” podcast, created by NotebookLM, are based on “Strong winter cooling over the Irminger Sea in winter 2014–2015, exceptional deep convection, and the emergence of anomalously low SST” by de Jong and de Steur. (2016). This research investigates the extraordinary deep convection observed in the Irminger Sea during the winter of 2014–2015. While... Continue Reading →

A Stalling Engine: How “Shoaling” of the Ocean’s Conveyor Belt Accelerates the Decline of Ocean Heat Transport

This blog post and the “Deep Dive” podcast, created by NotebookLM, are based on “Future Shoaling of the AMOC and Its Impact on Oceanic Heat Transport to the Subpolar North Atlantic” by Lee et al. (2026). Research by Lee et al. (2026) investigates how greenhouse gas emissions will alter the Atlantic Meridional Overturning Circulation (AMOC) and its ability to move heat... Continue Reading →

Nordic Seas are the Primary Driver of the AMOC

This blog post and the “Deep Dive” podcast, created by NotebookLM, are based on “Volume, Heat, and Freshwater Divergences in the Subpolar North Atlantic Suggest the Nordic Seas as Key to the State of the Meridional Overturning Circulation” by Chafik and Rossby (2019). Research by Chafik and Rossby identifies the Nordic Seas as the primary driver of... Continue Reading →

Oceanic Slow-Lane: Why the Subtropical Gyre Holds the Key to How the ITCZ Responds to AMOC Slowdown

This blog post, created by NotebookLM, is based on “On the Atlantic extratropical-tropical teleconnection in response to external freshwater forcing” by Joshi an Zhang (2026). This research study utilizes a coupled climate model to investigate how a massive influx of freshwater in the North Atlantic triggers a chain reaction that shifts the Intertropical Convergence Zone (ITCZ) southward. The authors demonstrate that... Continue Reading →

A Highway of Heat to the Arctic: Why a Vital Ocean Current Is Losing Its Chill

This blog post and the “Deep Dive” podcast, created by NotebookLM, are based on “Reduced cooling in the Norwegian Atlantic Slope Current: investigating mechanisms of change from 30 years of observations” by Baumann et al. (2025). This research analyzes thirty years of hydrographic data to investigate why Atlantic Water in the Norwegian Atlantic Slope Current is cooling less as it travels... Continue Reading →

The Atlantic’s Long Reach: How tropical Ocean Warming Fuels Greenland’s Melt

This blog post and the “Deep Dive” podcast, created by NotebookLM, are based on “Surface warming over Greenland amplified by remote forcing from tropical Atlantic” by Zhang et al. (2025). Recent research indicates that sea surface temperature variability in the tropical North Atlantic acts as a remote driver for the significant warming of the Greenland... Continue Reading →

Fingerprint Of Global Warming On Tropical Oceans Has Emerged In The Atlantic—While the Pacific Stays Cool

This blog post and the “Deep Dive” podcast, created by NotebookLM, are based on “Emergence of the enhanced equatorial Atlantic warming as a fingerprint of global warming” by Dong et al. (2025). Summary: This research identifies enhanced equatorial warming (EEW)—a pattern where sea surface temperatures near the equator rise faster than the surrounding tropics—as a... Continue Reading →

The Nordic Seas Overturning Circulation Is Set to Rebound After the 2040s

This blog post and the “Deep Dive” podcast, created by NotebookLM, are based on “Future strengthening of the Nordic Seas overturning circulation” by Årthun et al. (2023). When we talk about climate change and the ocean, one of the most prominent stories is the weakening of the Atlantic Meridional Overturning Circulation (AMOC). This vast system... Continue Reading →

A Climate ‘Tug-of-War’ Has Paused the Atlantic Current’s Slowdown

This blog post and the “Deep Dive” podcast on a paper “A pause in the weakening of the Atlantic meridional overturning circulation since the early 2010s” by Lee et al. (2024) was created by NotebookLM. Deep Dive Podcast “Atlantic Current Stability Is Borrowed Time” powered by NotebookLM: Introduction: The Ocean's Alarming Story Just Got More... Continue Reading →
